Ni 0 -catalyzed cross-coupling of aryl methyl ethers with amines is described. The use of an N-heterocyclic carbene as a ligand and NaOt-Bu as a base promotes the amination of anisole derivatives via the cleavage of normally unreactive aryl carbon-oxygenbonds.

heterocycles such as indole, carbazole, pyrrole, 10‐phenothiazine, and 10‐phenoxazine were shown to be feasible coupling partners under this catalytic system. The described reaction conditions tolerate a wide range of functional groups and allow an array of aromatic amines as well as unsymmetrical amine products to be easily accessed from the various phenolic derivatives. Interestingly, this catalyst
A nickel-catalyzed, efficient C-N bond reduction of aromatic and benzylic ammonium triflates has been developed using sodium isopropoxide as a reducing agent. The high efficiency, mild conditions, and nice compatibility...

Photoredox catalysis is a versatile approach for the construction of challenging covalent bonds under mild reaction conditions, commonly using photoredox catalysts (PCs) derived from precious metals. As such, there is need to develop organic analogues as sustainable replacements. Although several organic PCs have been introduced, there remains a lack of strongly reducing, visible-light organic PCs
